I got some issues to deploy my application.
Environment: Ubuntu 10.04, Tomcat 7.02 (Install from archive from tomcat site, not from repositories), server is run and
I have been able to replicate your problem.
There are 2 workaround I can suggest after tinkering around with combinations of appBase and docBase. Looks like the two do not operate together.
Remove the appBase from server.xml and specify the full path to the web app in docBase in the $CATALINA_HOME/conf/Catalina/java.dev/siloc.xml
I assume your value will be /home/krasilich/java/siloc/web/siloc.
Note: specifying only up to the parent folder /home/krasilich/java/siloc/web/ will show you a directory listing of the parent folder
In $CATALINA_HOME/conf/Catalina/java.dev/siloc.xml
remove the docBase and keep only <Context/>
Tomcat infers the webapp name siloc from the $CATALINA_HOME/conf/Catalina/java.dev/siloc.xml and it looks for the webapp named siloc in the appBase.
This allows java.dev:8080/siloc/ to work provided you also change the appBase in server.xml to the parent folder of your webapp siloc.
In response to why manager works, same reason - there is no docBase in the manager.xml
I am trying other combinations of docBase but any value I give throws the
WARNING: A docBase ... inside the host appBase has been specified, and will be ignored
So my conclusion is to remove the docBase. This is not a good idea - since the full path to parent folder is then hardcoded in server.xml.
